30 - 6 (x + 3) + 2x = 8

I believe the correct answer would be the first X=1 and the second X=1

Basically they both equal 1

X=1

Step-by-step explanation:

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

the solution is h=10 because you add 9 to each side of the equation.
